Hey guys, can I use a htc charger to charge the s2, I understand the output is different between s2 charger and htc charger, will it pose a problem to the battery?
no problem.
Some info:
A charger does not push a certain current either, the phone uses as much as it wants as long as it is same or less than the current rating on the charger.
And if the charger provides less than the phone wants, then the phone adapts to this as well.
Oki, if let's say the htc charger out is 1.0mah, and the samsung charger is 0.7mah, is it still alright to use the htc charger?

Yes you can just look under your battery once removed on your serial label
Erm.. what to look for?
I only see 3.7V and 1650mAh.
That's all.

No problem.
I'm charging my phone with the following chargers: 1.2A Nokia charger, 1A Nokia charger, 0.7A Samsung charger, 0.55A noname car charger, and some USB cables providing 0.5A.
And I also understand the electrical theory regarding this so this is ok both in practice and theory

The higher the A rating, the faster the battery will charge, but this also will heat the battery more, reducing it's lifespan. Slower charges are annoying, but preferred for battery longevity.
Can I check what A rating is iphone charger? I'm planning to plug in microUsb to charge my s2 at work and leave the stock charger at home.
So want to check again, if 1A charger is suitable for S2?
Just to add on. When I'm charging my S2 using stock charger and playing grand prix story, the percentage of the battery actually decreased. Is it due to the 0.7A supplied by the stock charger?

The phone only allows 650mA? or so into the battery, so anything above that is usually wasted. If you're playing graphically intensive or CPU intensive games most likely the charge rate can't match the drain rate, so slower charging or draining in your case.
S2 only allows 650mA? So even if I have a 1A charger, it won't be able to charge up fast too?

No it won't charge it faster.

I use my gfs HTC charger, mines fine
You can use any charger but, from what I've heard, if the output is higher than what is recommended for your phone, the battery life will be reduced.

This is not quite true.
The voltage of mini USB type chargers should always be 5volts. The current rating (amps) varies depending on the charger. Using a charger to charge a device to with a current rating lower than the current rating of the charger will make no difference. However using a charger to charge a device that requires a higher charging current could result it the device taking a longer time to charge and may not fully charge at all.
So most chargers will be fine to charge your phone. However if the charger current rating (amperes) is too low, you may find that if your using your phone while charging you could find the the battery will charge very slowly or even discharge (more likely when using something like navigation app). Both circumstances will make no difference to the health of the battery.
Hey guys I just received my wireless charger from android central (the Zens one) and I had a question the amps and volts on the wireless charger are far off that of the nexus 4s stock charger. Does this matter as it is wireless charging and not the stock method of charging? If not how bad is this for my battery I do not want to ruin my battery as the batter is not removable. Stock android charger is 5.0 V and 1.2 A, new charger is 12 V and 1 A
Please need some serious help
From my current understand of the Qi standard, your N4 will tell the pad what voltage it should get and the pad will send it at what is needed for your device. Plus I think I have seen people post videos of using the Zens brand charger with the N4 with no problems.
Some schematics and more info if you are curious.

Does anyone know what is the maximum possible charging current when using a wireless charging setup?, or does anyone know what all the wireless charging specs are for the GS4, like maximum charging current? I bought a charging insert coil, and my phone charges at 640mah with it. I was trying to get one that gave me a little more juice, and bought a different one which it says has a 1000mah output capacity, but it still charges at 640mah. Currently I have ktoonz kernel and a fast charge enabler app, turning fast charge on and off does not make any difference. Also, searching online does not give me specific answers related to wireless charging specs on the GS4.
thanks.
My N7 has some kind of issue with the battery. I have it plugged into my N6 charger, which charges my N6 VERY quickly but at 20% my N7 says ETA to full charge is 9 hours! This has been happening for a while. Is this just due to crap hardware?
Get the app "Ampere" and verify that your charger is putting out more than the tablet is consuming. First, run the app while not charging to see what the normal discharge rate is. Then plug it in and Ampere will show the charging rate. Your charging rate will always be your charge minus discharge. If your normal discharge is 480mA, and your charger is a 2A, then expect to see about 1500mA of charge rate when plugged in.
Be advised that I have yet to find a charger that puts out what it claims to be. Several of my name brand 1A chargers only put out about 700mA, confirmed with 3 devices using this app and one other. My best (most honest) charger is the 2.1A charger that came with my Samsung Galaxy Tab Pro 8.4. The N7's OEM charger is quite good too.

Thanks. I'll check it out later on today. Hopefully this will solve the battery drain when the screen is on and the tablet is charging issue too...
Put your tablet in "airplane" mode or power down the unit, that also helps out without many things running...
Using s8 fast charger it is rated as 5v , 2a im worried as is dont have lg original charger which supports 1.8a(fastcharge). My phone also got hot on samsung adapter . Should i buy original or its nothing to worry about. Kindly need advice.
AFAIK, there will be no difference. The chip controls how much energy is delivered to the battery, and even if you use a 3a charger, the phone itself will limit the maximum energy delivered so it doesn't affect battery.
It's normal that the battery gets hot on fast charge (even in normal charge) Just try to avoid using the phone or charging in a hot environment so the battery doesn't go further than ~40°C more or less.

The original one is 9V 1.8A so there won't be any problems with the Samsung one.
